Description

  The present invention relates to a seat formed by supporting a seat cushion body formed by arranging a plurality of seating portions side by side with a base frame portion. More specifically, the seat comfort is improved by suppressing the influence from adjacent seating portions. Regarding seats. The seat of the present invention is installed, for example, on a train or a bus.

  In trains, buses, and the like, a seat in which a plurality of seating portions are provided side by side along a wall in the traveling direction of the train (the length direction of the vehicle) is often used.

In the conventional seat, as illustrated in FIG. 5, the seat cushion body 1 </ b> P having a plurality of seating portions 10 </ b> P is integrally formed. Therefore, when a person is seated on a certain seating portion 10 </ b> P, the weight thereof It has been pointed out that the seating surface of the seating portion 10P sinks, and as a result, the seating surface of the adjacent seating portion is pulled and the elasticity is cured.
In addition, even when the adjacent seats are vacant, the elasticity of the seating part sandwiched between the seating parts on both sides is less than the seating part at the end of a series of seats where there is no seating part on either side. Therefore, it has been pointed out that it is slightly hard and has a poor seating feeling.
On the other hand, it has been pointed out that the seating portion at the end of the series of seats has a different pulling force from each side, so that the body of the seated person tends to tilt toward the end.
Japanese Patent Laid-Open No. 2010-280234 (Patent Document 1) describes a railcar seat that can be satisfactorily seated and easily cleaned even if people of various physiques sit down, from children to adults. Yes.

JP 2010-280234 A

The object of the present invention is to eliminate the above-mentioned phenomenon.
That is, the seating feeling of each seating part is not affected by the adjacent seating part, and a good seating feeling can be obtained regardless of whether a person is seated in the adjacent seating part or not. The purpose is to be able to.

  The configuration of the present invention will be described in the following [1] to [4]. In this section ([Means for Solving the Problems]) and the next section ([Effects of the Invention]), reference numerals are given for ease of understanding, and the present invention is configured by reference numerals. It is not intended to be limited.

[1] Configuration 1
A seat cushion body 1 formed by arranging a plurality of seating sections 10 and 10 side by side; and a base frame section 2 including a front frame body 21 that supports a front end portion of the seat cushion body 1.
Each of the seating portions 10, 10 of the seat cushion body 1 is connected to each other at a front end portion supported by the front frame body 21 at a portion partitioning between the adjacent seating portions 10, 10, The rear side excluding the connected part is separated from each other by the through slit 11.
A seat characterized by that.
As the front frame body 21, for example, a pipe material can be used.

In the configuration 1, “the upper surface of the seat cushion body 1 is covered with a skin cover 3, and the skin cover 3 is adjacent to the seating portion 10, which forms the through slit 11 in the portion of the through slit 11. It is also possible to constitute “seats inserted into the through slits 11 from the respective seating portions 10 and 10 so as to cover the 10 slit side surfaces 101 and 101”.
Further, in the above configuration, “the skin cover 3 at the part of the through slit 11 is inserted into the through slit 11 from each of the adjacent seating portions 10, 10, and then in the through slit 11. It can also be configured as “seats that are continuous”.
Alternatively, in the above configuration, “the skin cover 3 at the site of the through slit 11 is inserted into the through slit 11 from the adjacent seating portions 10 and 10, and then the respective tips 311 and 311 are inserted. It is also possible to constitute “a seat that is folded from the lower end of the through slit 11 toward the lower surfaces 105 and 105 of the seating portions 10 and 10”.

[2] Configuration 2
In configuration 1,
The base frame portion 2 further includes a rear frame body 22 that supports a rear end portion of the seat cushion body 1, and one or two or more S are interposed between the rear frame body 22 and the front frame body 21. A spring 4 is stretched in the front-rear direction to support the seat cushion body 1.
A seat characterized by that.
[3] Configuration 3
In Configuration 1 or Configuration 2,
A concave groove 12 continuous from the through slit 11 is formed on the upper surface of the portion that is a portion that partitions between adjacent seating portions of the seat cushion body 1 and that is provided continuously.
A seat characterized by that.
[4] Configuration 4
In any of Configuration 1 to Configuration 3,
The length of the through slit 11 in the front-rear direction of the seat cushion body 1 is longer than the length of the connected portion where the through slit 11 is not provided.
A seat characterized by that.

The configuration 1 includes: a seat cushion body 1 formed by arranging a plurality of seating sections 10 and 10 side by side; and a base frame section 2 including a front frame body 21 that supports the front end portion of the seat cushion body 1. And each seating portion 10, 10 of the seat cushion body 1 is connected to each other at a front end portion supported by the front frame body 21 at a portion partitioning between the adjacent seating portions 10, 10. Since the rear side excluding the connected portion is a seat separated from each other by the through slit 11, the rear side (back side) of the seat cushion body 1 is separated from the adjacent seating portion. And can move up and down freely. For this reason, even when a person is seated on an adjacent seating portion and the upper surface sinks due to its weight, the surface of the seating portion is not pulled toward the sinking adjacent side, and the seating feeling is not stiffened. Can maintain good sitting comfort.
In the configuration 2, the base frame portion 2 further includes a rear frame body 22 that supports a rear end portion of the seat cushion body 1, and the rear frame body 22 and the front frame body 21 are arranged in the configuration 1. 1 or 2 or more S springs 4 are stretched in the front-rear direction to support the seat cushion body 1, and the elasticity of the seat cushion body 1 is supported by the S spring 4. In this structure, the assistance is performed for each seating section 10 regardless of the adjacent seating section. For this reason, the effect of the structure 1 can be exhibited further favorably.
Configuration 3 is any one of Configurations 1 to 2, and is a portion that partitions between adjacent seating portions of the seat cushion body 1, and the through slit 11 is formed on the upper surface of the connected portion. Since this is a seat in which a continuous groove 12 is formed, the influence from the adjacent seating portion can be reduced even on the front end portion side without the through slit 11, and the effects of the configurations 1 to 5 and the like are further improved. it can.
In the configuration 4 according to any one of the configurations 1 to 3, the length of the through slit 11 in the front-rear direction of the seat cushion body 1 is the continuous arrangement in which the through slit 11 is not provided. Since the seat is longer than the length of the portion, a better sitting comfort can be obtained.

The seat cushion body with which the seat of an embodiment is equipped is shown, (a) is a perspective view and (b) is a top view. The seat cushion body of FIG. 1 is shown, (a) is a top view, (b) is a cross-sectional view along line BB in (a), and (c) is a cross-sectional view along line CC. It is a principal part enlarged view of Drawing 2 (c), (a) is a case where a skin cover continues in a penetration slit between adjacent seating parts, (b) is a case where it is not continued but is folded by the lower surface of each seating part Indicates. The side view (a) which shows the seat of embodiment, and the disassembled perspective view (b) which shows a mode that S spring is attached to the seat of embodiment. The conventional seat cushion body is shown, (a) is a perspective view, (b) is a top view.

Embodiments of the present invention will be described with reference to the drawings.
The seat of the present embodiment is a seat for a railway vehicle, and a seat cushion body 1 (see FIG. 1) having three seats 10, 10, and 10 provided side by side and a backrest 5 (see FIG. 4). Is mounted on a base frame portion constituted by the front pipe 21 and the rear pipe 22 as shown in FIG. Here, the front pipe 21 is an example in which the front frame body 21 described in the configuration 1 is embodied, and the rear pipe 22 is an example in which the rear frame body 22 described in the configuration 5 is embodied. .

  As shown in FIG. 1, the seat cushion body 1 is arranged between the adjacent seating portions 10-10 (sites separating the adjacent seating portions), and the rear side (rear end) of the adjacent seating portions 10-10. A through slit 11 that separates a portion near the rear end including the portion. This through-slit 11 is not provided at the front end (the part to be placed / mounted on the front pipe 21), and the rear side (the rear end including the rear end) excluding a certain predetermined range on the front end side. (Part close to the part). That is, as shown in FIG. 2, up to approximately 3/4 of the rear cushion (back side) in the front-rear direction (depth direction) of the seat cushion body 1 is separated by the through slit 11. The through slit 11 is not provided in a range of about ¼. As shown in FIG. 2B, a recess 12 is provided in a range of about 1/4 of the front side so as to be continuous with the through slit 11. In the illustrated example, the “certain predetermined range” is a range of about ¼, but this may be the same as or different from the width of the front pipe 21. In other words, the range in which the through slit 11 is provided may be a range in which an operation and effect described later (an operation and effect that blocks the influence from the adjacent seating portion) can be exhibited. About 90%, preferably about 60-90%. This range includes other materials such as the material of the seat cushion body 1, the structure of the seat cushion body 1 (layer structure, integral type, etc.), the elasticity applying structure such as the S spring provided below the seat cushion body 1, etc. Factors are also taken into consideration.

  Since it is configured as described above, each seat 10 can move up and down independently like a piano keyboard. That is, even if a person sits on the adjacent seating portion and the seat surface sinks with the weight, the sinking is blocked by the through slit 11 and is not transmitted to the adjacent seating portion. Therefore, the seating surface of the seating portion is not pulled due to the sinking of the adjacent seating portion, and a good seating feeling can be maintained. In the case of the present embodiment, the “effect of blocking the influence from the adjacent seating portion” played in this way is continuous with the through slit 11 at the front end portion where the through slit 11 is not provided. By providing the recessed part 12, it is exhibited more satisfactorily.

  The surface of the seat cushion body 1 is covered with a skin cover 3 (not shown in FIG. 1 and FIG. 2). As shown in FIG. 2, the insertion slits 11 are slightly inserted into the through slit 11 and are continuous with each other at the slightly inserted height. This height is determined as a height at which the skin cover that is continuous in the through slit 11 does not hinder the above-described “effect of blocking the influence from the adjacent seating portion”.

  When the skin cover 3 is provided at the site of the through slit 11 as described above, there is an effect that the work process for mounting the skin cover 3 to the seat cushion body 1 can be performed relatively easily. Further, since the through slit 11 is closed by the skin cover, there is an effect that dust that has entered the through slit 11 can be easily removed.

  Instead of the configuration shown in FIG. 3A, a configuration as shown in FIG. That is, instead of inserting the skin cover 3 into the through slit 11 and continuing it, the tips 311 and 311 of the skin cover inserted from the adjacent seating portions are connected to the seating portions 10 and 10 from the lower end of the through slit 11. You may provide so that it may fold in the lower surface 105,105 side. When provided in this way, the above-mentioned “effects of blocking the influence from the adjacent seating portion” can be reliably achieved. In addition, there is an effect that the dust that has entered the through slit 11 can be collected by dropping it below the seat.

  In the present embodiment, the seat cushion body 1 is mounted on the base frame as shown in FIG. As shown in FIG. 4 (b), the base frame portion is constituted by a front pipe 21, a rear pipe 22, and side frame bodies 23 at both left and right ends (a left side frame body is not shown). It has a substantially rectangular shape, and there is no member in the central part surrounded by these, and it is a hole. In the illustrated example, the side frame bodies 23 are provided at both the left and right ends, but may be appropriately provided at an intermediate portion between them (an appropriate portion of the “hole”). For example, a frame similar to the side frame 23 may be provided at a boundary portion between adjacent seating portions. In the base frame portion having such a configuration, the S spring 41 is bridged over the hooks 410, 410 on the front pipe 21, and the four hooks 421, 421, 421, 421 of the front pipe 21 and the four hooks S springs 42, 42, 42, 42 are bridged between the four hooks 422, 422, 422, 422 of the rear pipe 22 corresponding to. That is, it is bridged back and forth. Here, each S spring is slightly curved so as to protrude upward when no load is applied. Further, a portion between the hooks 410 to 410 corresponds to one seating portion 10.

The seat cushion body 1 is placed and mounted on the S springs 41, 42, 42, 42, 42 as described above. Thereby, the seat of this Embodiment is comprised.
Because of this configuration, when a person sits on a certain seating portion 10, the seating surface of the seating portion 10 sinks due to weight, but the sinking is blocked at the site of the through slit 11 (and the recess 12). It is not transmitted to the adjacent seating part. For this reason, the event that the seating surface of the adjacent seating part is pulled and the feeling of elasticity at the time of seating is cured is also prevented. In addition, since both sides of each seating part are separated from the adjacent seating parts and the structure on both sides is the same, the elasticity of the seating surface is also equivalent, and the body of the seated person tends to tilt to either side The phenomenon of becoming is also prevented.

In the above, the material of the seat cushion body 1 is not mentioned, but as the material, a known material, for example, integral molding of urethane or a layered structure of a resin sheet (eg, see Japanese Patent No. 4868948) Etc. can be used as appropriate. Moreover, a well-known shape can be used suitably also as the shape (shape of parts other than the penetration slit 11 and the recessed part 12, for example, back surface shape etc.).
In the above description, the S spring is used, but a known elasticity applying member such as a coil spring or a cloth spring can be used instead of or together with this.
